Lesson 36: Second Law of Thermodynamics

Question 1

This states that if the physical process is irreversible, the entropy of the system and the environment must increase.

Answer 1

Second Law of Thermodynamics

Question 2

This is a type of engine that produces macroscopic motion from heat.

Answer 2

Heat Engine

Question 3

Describes how heat engines turn gasoline into motion.

Answer 3

Otto Cycle

Question 4

This was originally designed by Alphonse Beau de Rochas.

Answer 4

Otto Cycle

Question 5

State the Internal Combustion Strokes.

Answer 5

• Intake
• Compression
• Ignition
• Exhaust

Question 6

This is named after Rudolf Diesel, any internal-combustion engine in which air
is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston.

Answer 6

Diesel Engine

Question 7

This is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected.

Answer 7

Fuel

Question 8

This is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment.

Answer 8

Adiabatic Process

Question 9

This process involves the volume is held constant.

Answer 9

Isochoric Process

Question 10

This is a process occurring at constant pressure.

Answer 10

Isobaric

Question 11

This is a totally reversible cycle which consists of two reversible isothermal processes and two isentropic processes.

Answer 11

Carnot Cycle
